Application filed August 14, 1890. Serial No. 361,988. (Np model.)

To all whom it may concern.-

Be it known that I, NEILL A. CAMERON, a citizen of the United States ofAmerica, residing at Blossom,in the county of Lamar and State of Texas,have invented certain new and useful Improvements in Balance or FlyIVheels; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon,whieh form a part of this specification.

This invention relates to improvements in balance or fly wheels, and isadapted to be applied to many different classes of machinery.

In the accompanying drawings I have illustrated myinvention applied to ahorse-power, in which- Figure 1 is a side elevation; Fig. 2, a sectionalview taken through the line 50 as, Fig. 1.

The object of myinvention is to pi ovide an improved balance or fl ywheel in which I make use of weights carried by spring-arms and meansfor holding the weighted springarms on one side of the wheel near thecenter thereof, said arms being released so as to be located fartherfrom the center of the wheel on the opposite side, and in carrying outmy invention I provide the fly-wheel with a series of radiatingspring-arms having notched ends with which spring-bars carrying weightsare adapted to engage; also, upper and lower grooved disks foralternately causing the engagement and releasing of the weightedspring-bars from the notched spring-arms.

In the drawings, A refers to a suitable frame, which maybe a part of ahorse-power or other machinery, the main shaft Ct thereof carrying acentral grooved roller B, while the shaft b carries a similar groovedroller 0. Between these shai ts CL and b is located a shaft 0, uponwhich is mounted the fly or balance wheel D. The shafts c and d may besuitably geared to each other by cog-wheels g, located on said shafts cand d, the shafts 0. and I) being connected by a belt h,which passesover pulleys on said shafts, the latter revolving in unison. The wheelD, mounted on the shaft 0, has secured to the periphery thereof a seriesof radiating spring-arms E, which are provided with notches or catchese,with which the tan gentially-located weighted spring-bars F engage atthe proper time. These tangential weighted spring-bars carryat theirouterends transverse weights IV, and their outward movement from'theshaft cis limited by bails or staples f. The rollers 13 and O aresimilarly constructed, having a central recess of sufficient size topermit the ends of the springarms E to pass into these recesses, and oneof these rollers, preferably the upper one 0, has a hub c of slightlylarger diameter than the hub b of the lower roller In operation,when thewheel D turned in the direction indicated by the arrow 1, theroller-disk B will be rotated in the direction indicated by the arrow 2,either by the belt connecting the shafts a and b, or by frictionalcontactof the spring-arms therewith. As the wheel D rotates, the outerends of the springarms E will pass into the recesses in the roller B,and the transverse weights IV, contacting with the peripheries of saidrollers, will move the weighted spring-arms inwardly to engage with thenotched ends of the spring-arms E, thereby holding the weights nearerthe center of the wheel than normally. As the springarms and weightedspring-bars move upwardly, the spring-bars F contact with the periph cryof the upper roller O,while the outer ends of the spring-arms E strikeagainst the hub and are sprung back to release the weighted spring-bars,thereby permitting the weights to move outwardly a considerable distancebeyond the periphery of the wheel,thus gaining considerable amount ofpower by shifting the position of the weights,which on one side of thefly-wheel will be near the center and on the opposite sideconsiderablybeyond. It will be obvious that it will not be necessary toconnect the shafts a and b by pulleys and belts, as shown, though it isdesirable to connect the main shaft with the wheel or pulley carryingthe shifting weights hereinbefore described.

Having thus described my invention, I claim- 1. The improved fly orbalance wheel herein shown, the same being provided with a series ofradiating notched arms and a correspond in g series of tangentialweighted bars, in combination with the rollers B and C, substantially asshown, and for the purpose set forth.

2. In combination with a wheel D,carrying a series of radiating springarms having notches, a series of tangential weighted springbars F, andoppositely-arranged rollers B and 0, having central recesses and hubs ofdiffer ent diameters for locking and releasing the weighted spring bars,substantially as set forth.

3. A fly-wheel D, provided with a series of radiating spring-arms havingnotches on their faces, tangential weighted spring-bars F, adapted toabut against the peripheries of the rollers B and C, so as to bealternately engaged with and released from the radiating spring-arms E,and bails or loops f for limiting the upward movement of the weightedspring-bars, substantially as. shown, and for the purpose set forth.

4:. In combination with a wheel D, having secured to the peripherythereof spring-arms E, with notched ends, spring-bars F, havingtransverse weights which engage with the spring-arms E, rollers B and O,centrally recessed, as shown, and provided with hubs of dilferentdiameters, so that the spring arms E can pass one of said bars withoutengaging therewith, while they engage with the opposite hub and are heldout of engagement with the weighted spring-bars, substantially as shown,and for the purpose set forth.

5. The combination of a fly-wheel, spring catch-arms, weightedspring-bars, and means, substantially as shown, for causingautomatically the engagement and release of the weighted spring-barsfrom the catch-bars, so that the weighted bars will be held near thecenter of the wheel while on one side and a considerable distance beyondwhen released, for the purpose set forth.

In testimony whereof Iaffix my signature in presence of two witnesses.
